Description

Apparatus for manually generating a spiral packaging material

The invention relates to a device for manually generating a spiral-shaped packaging material.

There are a number of possibilities for providing spiral-shaped packaging material, which is frequently formed on the basis of a fibrous material web, in particular a paper web, for manual further processing. If the packaging material is wound into a roll, it can be wound and / or withdrawn generically from either the outside or the inside of the roll. In the invention, the packaging material is unwound from the inside of a roll and / or peeled off.

In AT 402 496 B, which relates to a proven method for the production of packing for packaging purposes, a carrying device in the form of a movable dresser is described. The dresser has a console on the side near the bottom, on which a first roll with vertical winding axis is placed. The top of the dresser has two semi-circular ribs, in which a second roll with a horizontal winding axis is inserted. Packaging material can be unwound by the user from the insides of both rolls by passing the stocking material from the first roll through the second and then draping the material from both rolls tubularly. Adjacent to the second roller, there is provided on the top of the dresser a cutting device, which is realized by a hand lever shears to divide a withdrawn packaging material tube into individual sections. For this purpose, the user must first open the scissor lever with one hand, then pass the packaging material with the other hand through the opened scissors and then operate the scissors lever. This is cumbersome and dangerous because the user has to reach with one hand through the opened shear area and peel off the packaging material, with each passing risk of injury, especially if the user is careless and releases or moves the scissors lever. The chest of drawers takes up a lot of space and can only be positioned adjacent to the working surface of the user with a static output direction. The well-known dresser is also disadvantageous in that for providing dense packaging material two rolls of paper be needed, which increases the cost of the device.

Annielderseitig the need has been recognized to provide a device for manually generating a spiral-shaped packaging material, which should consume as little space in the workspace of the user. In addition, it is desired that the packaging material should be provided in close proximity to the user's work surface, and that the user be free to choose the position and orientation of the material output and also change it during use.

It is an object of the invention to overcome the disadvantages of the prior art, in particular to provide a cost-effective device for manually generating a spiral packaging material in which there is a low risk of injury that can be arranged in different orientations, safe to use and as compact as possible without the equipment of the device with a fibrous material web roll complicated and or tedious.

This object is solved by the features of claim 1.

Thereafter, an apparatus for manually producing a packaging material comprises a receptacle and an adjoining axial holder with a dispensing opening and a tapered inner wall portion. The packaging material can be, for example, paper, waste paper, soda kraft paper, soda-blended paper or roll corrugated cardboard. The receptacle allows at least partially circumferentially encompassing a fiber material web roll, which defines an axial direction and forms an inner side from which the fiber material web is drawn off to form the packaging material. The inside of the roll is formed by the innermost winding of the fibrous material web and includes the end of the fibrous material web which is withdrawn from the roll to form the packaging material. The other, opposite end of the fiber material web is located on the outer periphery. By peeling or unwinding the fibrous web from the inside of the roll, the user only has to apply force to move the desired amount of packaging material and not overcome the inertia of the entire fibrous web roll, allowing the user to quickly strip the desired length of packaging material from the fibrous web roll at the same time precise metering allowed, since the inertia of the fiber web roll to complete a deduction process must not be slowed down. An Axialhalterung connects to the recording, where a front in the withdrawal direction axial end face of the fiber material web roll is held. When the fibrous material web roll is in the receptacle, it is supported radially on the receptacle and axially on the inside of the axial mount. In the axial holder, a discharge port for discharging the packaging material is formed in the axial direction. The winding axis of the fibrous material web roll preferably extends through the dispensing opening. However, the dispensing opening can also be configured slot-shaped, for example, and can not be arranged in alignment with the winding axis of the fibrous material web roll. The windings of the fibrous material web roll are formed approximately circularly around the winding axis of the roll, which predetermines the orientation of the axial direction. Furthermore, the axial holder has an inner wall section facing the front side of the fibrous material web roll, which tapers towards the dispensing opening. As a result of the taper, the fiber material web roll resting on the inner wall section is preformed in the discharge direction, so that the innermost winding of the fiber material web roll is offset in the axial direction from the second and to every other, in particular the outermost, winding. As a result, the fiber material web is guided to the discharge opening during removal so that the web drawn off to form the packaging material does not first undergo a change in direction directly at the delivery opening, but the change in direction has already been initiated beforehand so as to avoid unwanted tearing off of the fiber material web or of the packaging material ,

The inner wall section preferably tapers in a funnel shape in the axial direction towards the dispensing opening. In particular, the funnel shape can taper constantly, increasingly, or decrease, that is to say preferably be conical or frustoconical, trumpet-shaped or bulbous. The rejuvenation can for example also have a straight or crooked pyramidal shape. The Axialhalterung may also have a plurality of tapered inner wall sections, which have different shape. In particular, the inner wall section is rotationally symmetrical. Also, the entire axial support may be substantially rotationally symmetrical and / or have a substantially constant wall thickness.

A rotationally symmetrical, frusto-conical funnel shape is particularly easy to manufacture and thus particularly cost-effective. In addition, a funnel-shaped inner wall portion of an axial support allows a well-defined guidance of the fiber material web roll or the withdrawn packaging material from the roll to the discharge opening, so that Premature tearing off of the fiber material web due to an unmediated strong change in direction of the web at the dispensing opening is avoided.

In a preferred embodiment, the opening angle of the inner wall portion is at most 150 °, in particular at most 100 ° and at least 30 °, in particular at least 70 °. A small opening angle of the inner wall portion allows the paper web to be accurately guided toward the discharge opening and causes the packaging material to be spiral after peeling, whereby the packaging material is already compact and precompressed when it is dispensed so that it is particularly easy to provide a dense packaging material. On the other hand, a large opening angle of the inner wall portion of, for example, 135 ° causes the packaging material to emerge from the dispensing opening in an increasingly elongated form, as the spiral turns move farther and farther apart, which is particularly suitable for providing packaging material that is rather flat. In addition, a large opening angle of the inner wall portion has the advantage that when aligned means for manually producing a packaging material with output direction down, the mass of the fibrous material web roll is at least partially supported by the inner wall portion can be avoided by a large opening angle that the paper web of the roll alone their mass and gravity slips through the dispensing opening without a user deliberately pulling off packaging material.

Preferably, the opening angle of the inner wall portion between 85 ° and 95 °, in particular about 90 ° is large. Surprisingly, allows an opening angle of the inner wall portion in the range between 85 ° and 95 °, in particular 90 °, a particularly flexible and at the same time less error-prone handling of the device, since it has been shown that an opening angle of about 90 ° on the one hand an effective guidance of the packaging material for dispensing opening and on the other hand, an opening angle of 90 ° is sufficiently large, in order to avoid even with oblique to vertical arrangement of the recording that the fiber material web roll unrolls independently and falls out of the discharge opening.

Preferably, the receptacle on the axial support is in particular releasably attached. For example, recording and Axialhalterung be carried out in one piece, which simplifies the assembly, or be releasably connected to each other, so that the Axialhalterung can be replaced. In a preferred embodiment, the Axialhalterung on at least one mounting collar, in particular a front and / or a rear mounting collar. Characterized in that a mounting collar is provided on the Axialhalterung, the mounting of the Axialhalterung example, can be simplified on the recording and the provision of the mounting collar on the Axialhalterung allows the user to easily and without damaging the Axialhalterung to cause various components to attach to it.

Preferably, the rear mounting collar engages over the receptacle at least partially. This allows a particularly simple and quick mountability of the axial support on the receptacle and allows the user to switch between different axial supports as required or to separate an axial support from the receptacle to simplify the assembly of the recording with a new fiber material web roll. In particular, the receptacle and the Axialhalterung rotational body and coaxially arranged in the aufgehülptem.

Preferably, a mounting collar adjoins the inner wall section in the axial direction, so that further components, such as a blade for cutting off the packaging material, can be arranged in extension to the inner wall section. Preferably, a mounting collar is substantially cylindrical, thereby preventing the paper web from colliding with an edge of a mounting collar when unwinding from the circular roller.

In a further development of the invention has a mounting collar on a backdrop that forms with a movable bolt, for example, the recording a bayonet and / or a snap connection. A snap connection allows easy installation. A bayonet lock is easy to assemble and provides, for example, in the axial direction increased restoring forces, which is particularly suitable for devices in which the packaging material down we deducted, since when the Axialhalterung is fixed with a bayonet lock on the recording, is easily avoided in that the axial support bearing the roller drops or slips off the receptacle. Preferably, the inner wall section may be fastened to the receptacle with a first fastening collar with a bayonet closure suggested above, and opposite to the mounting. take a blade around the dispensing opening of the axial holder to be bolted to a second mounting collar.

In a preferred embodiment of the device, a cutting edge, preferably in the form of a ring gauge, in particular in the form of a full circumference, is arranged on the inner circumference of the dispensing opening. The inner circumference may, for example, have other shapes than a circular shape. If a cutting edge is arranged on the inner circumference of the dispensing opening, the device is particularly compact. If the cutting edge does not cover the entire inner circumference, the risk of injury to the user is particularly low and it is avoided that the fiber material web unintentionally comes into contact with the cutting edge during removal and accidentally tears off. A ring knife allows a particularly rapid production of packaging material with the device, for example, because the user can move a paper web in any direction away from the dispensing opening to separate it from the roll.

In a further development of the invention, the cutting edge has a plurality of teeth. The teeth may for example be integrated into the axial holder, for example when the axial holder is a plastic injection-molded part. The teeth may preferably extend at least partially radially inward and / or axially in the dispensing direction, in particular at an angle of approximately 45 ° to the axial direction. When the teeth extend in the radial direction, the tearing off of the packaging material from the roller is particularly energy-saving possible, while an axial extension direction of the teeth causes the risk of injury to the user when reaching through the dispensing opening of the device is particularly low, because when removing the packaging material no Injuries can occur through the teeth, even if the user comes into tangential contact with them. It has been found that an angle of about 45 ° to the axial direction causes a particularly good compromise between the risk of injury and the exertion of force.

In a preferred embodiment, the cutting edge has a mounting ring, which is realized in particular as a metal ring, which is externally mounted on the Axialhalterung. A mounting ring allows the user to quickly and easily replace a worn cutting edge with a new one. Preferably, the mounting ring can be releasably mounted on the front of a mounting collar, preferably with at least one screw, in particular with three or four. The cooperation of the mounting ring with the front mounting Collar of the axial support simplifies the installation of the cutting edge on the axial support for users considerably, so that a worn cutting edge can be replaced very quickly.

In a preferred embodiment of the invention, the dispensing opening is dimensioned large enough to permit a user to grasp through to grasp packaging material in the multi-finger device. With a sufficiently large dispensing opening, the user is not forced to push the paper web to form the packaging material cumbersome from behind through the dispensing opening should it break off once or if it is removed from the device for the first time after loading. For a quick and easy usability of the device, the dispensing opening is sufficiently large, so that the user can reach into it with at least two, preferably three, fingers or even with the whole hand to easily capture the packaging material without cumbersome movements. In particular, there are no, for example, movable or sharp-edged components between the fibrous material web roll and the dispensing opening, which make it difficult for the user to intervene and possibly even pose a risk of injury, such as toothed wheels.

Preferably, the inner diameter of the dispensing opening is greater than 2.5 cm, in particular greater than 5 cm or larger than 10 cm and / or smaller than 30 cm, preferably smaller than 15 cm, in particular smaller than 11 cm. In order for the user to be able to reach through the dispensing opening to grasp the packaging material, the inside diameter of the opening must be at least about 2.5 cm, and thus can reach in with the whole hand should it be larger than 10 cm. The dispensing opening is less than 30 cm, preferably less than 15 cm, so that the user, on the one hand, reaches in with his whole hand, but on the other hand unrolls the roll unintentionally through the dispensing opening. For example, if the packaging material has a particularly low coefficient of friction, the diameter of the dispensing opening may be less than 11 cm.

Preferably, the receptacle is substantially semi-cylindrical, so that it has a corresponding semi-cylindrical insertion opening for filling the receptacle of the device with a roller in the radial direction and in particular in the axial direction. Surprisingly, it has been found that a semi-cylindrical receptacle allows a particularly fast and less error-prone loading with a fiber material roll, such as a paper roll, as a user a fiber material roll during radial loading on secure the front end of the roll and at the bottom of the roll and insert the roll using both hands in the device without damaging the packaging material during insertion. The fibrous material web roll for forming the packaging material may alternatively be a paper or paperboard material, a plastic film, bubble wrap, metal foil, aluminum foil or a composite foil of several materials, which is wound into a roll. Unlike the loading in the axial direction of the user is not forced to wear the role on the outer circumference, the outer winding of the fiber material web roll often tears or slips. If the receptacle is half-shell-shaped, it can be equipped very quickly. By loading in the radial direction, the fiber material web roll can be inserted accurately into a corresponding cylindrical receptacle. In particular, the receptacle is at least partially shaped as a half shell. Half shells are cheap and easy to produce, for example, from tubular or flat sheet metal.

Preferably, the inner circumference of the receptacle corresponds to the outer circumference of the roller. If the outer circumference of the roller conforms to an inner circumference of the receptacle, a particularly secure mounting of the roller is realized, which allows the device to be moved, for example, vertically, horizontally and / or rotationally without any relative movement between the roller and the receptacle ,

In a development of the invention, a receptacle has a support section and / or a holding section. The holding section extends over at least half, ie 180 °, preferably over 190 ° of the cylinder circumference and causes a retention of the fiber material web roll in the radial direction and thus prevents, for example, that the fibrous material web roll unintentionally slips out of the device or rolls, such as when the device by the user is moved. Surprisingly, it has been shown that only a little more than half of the circumference of the fibrous material web roll has to be encompassed by the holding section, in particular about 190 °, in order to ensure that the fibrous material web roll does not unintentionally slip laterally out of the receptacle. At the same time, the flexibility of the holding section allows a simple loading of the device with a fiber material web roll.

A support portion of the receptacle extends over at most 180 °, in particular over 170 °, of the cylinder circumference in order to carry a part of the load of the fiber material web roll without hindering the assembly. A support section may be in the supply material discharge direction be arranged in front of or behind the holding section. It is also conceivable that a recording has a plurality of alternating support and holding section, which are arranged like a tooth or comb.

In a preferred embodiment, the holding portion is longer in the axial direction than the support portion. Surprisingly, it has been found that a particularly advantageous recording can be realized by providing a support portion which is longer than a holding portion, a stable support for a fiber material web roll, the recording remains elastic enough to equip the device easily and quickly can. If the receptacle comprises a plurality of supporting and holding portions, the summed length of the holding portions in the axial direction may be longer than the sum of the length of the supporting portion to cause the same effect.

In a preferred embodiment of the invention, the receptacle has an end stop for limiting the freedom of movement of a fibrous material web roll in the axial direction, which is arranged in the mounted state relative to the axial support on the receptacle and extends radially inwardly. Such an end stop ensures that the fibrous material web roll remains in the receptacle of the device even if the dispensing direction of the device is oriented obliquely upwards. Surprisingly, it has been found that the unwinding or removal of the fibrous material web roll obliquely or vertically upwards allows a particularly rapid removal and the device for manually generating a packaging material can be arranged to save space below a working plane of a user. In addition, it can be avoided by an end stop, that the fiber material web roll accidentally slips axially out of the recording when moving the device, so that the error rate of the device is reduced by an end stop.

Preferably, the end stop is formed as a fully circular plate. A roller has a circular base cross-section, which can be placed on a fully circular plate to save space with optimum support in the axial direction. In this way, the plate allows that it is also possible to arrange the device with dispensing direction vertically upwards. Preferably, the end stop, which may be a substantially circular plate, has along its outer edge at least one convex gripping recess which facilitates loading. The end stop is preferably realized not with solid material but with openings, so that the material costs are reduced and the user is enabled, with a quick glance through the openings, to quickly check how much packaging material is in the receptacle. The end stop is preferably formed like a grid, for example, the openings are square, rectangular, triangular, round or trapezoidal and arranged regularly. A lattice-like design of the end stop is advantageously stable, light and prevents the view of the contents of the device only insignificantly.

In a preferred embodiment, the receptacle has a flange which extends in particular radially away from the receptacle and through which extends perpendicular to the axial direction at least partially a pivot pin which defines a pivot axis about which the receptacle is pivotable. The receptacle-side flange can be fastened to the receptacle and, in particular, can be formed integrally with the receptacle. By a pivoting device, the user is allowed to arrange the recording of the device for handling at any angle. A pivot pin, which extends through two flange connections, can realize a pivoting device in a particularly simple and cost-effective manner.

In particular, the distance from the winding axis to the axis of rotation of the pivot pin substantially coincides with the distance of the winding axis to the pivot axis, so that the pivot axis does not intersect the winding axis and is skewed thereto.

Preferably, the pivot pin extends at least partially through a mounting flange and in particular a locking bolt extends, in particular parallel or coaxial with the pivot axis, at least partially through the receiving side flange and / or the mounting flange to define a pivot position. Preferably, the locking bolt has a thread. For example, the locking bolt may be screwed through a threaded bore of the receiving side flange and screwed against the mounting flange to determine the orientation of the device and thus the output direction

Preferably, the support structure-side flange and / or the mounting flange has a plurality, in particular 3, 5 or 7, preferably with the locking pin corresponding locking openings for determining the pivot position. If several locking holes are ready are set, the user can choose between the fixed by the locking openings pivot positions him most comfortable. The locking openings correspond in particular with the locking bolt. When a locking pin is inserted through a flange in a locking hole of the other flange, a positive connection between the bolt and the opening is realized, thereby achieving a particularly secure determination of a pivot position.

Preferably, the flange is arranged opposite the mounting opening on the receptacle. This results in a particularly favorable force flow for receiving the weight of the fiber material web roll by the pivoting device in the support structure, without the torsional forces acting on the pivoting device, so that the pivoting device can be realized inexpensively.

A development of the invention relates to a device for manually generating a packaging material, which comprises a support structure. The support structure may be formed as a table, in particular table leg or table top and / or as a stand. A stand can in particular be movable and preferably have at least one extension arm. If the device is connected to a table, which is usually available to the user anyway as a work surface, is connected, can be dispensed with additional cost-carrying support structure elements. A stand allows for flexible placement of the device with a roll of paper above or adjacent the user's work surface. For example, a movable boom can be used to move the device between work surfaces of two or more users.

Preferably, the support structure comprises a rotating device that allows rotational movement of the device about an axis of rotation that does not correspond to the axial direction. This has the advantage that a device can be quickly and easily rotated back and forth between multiple workstations.

Preferably, the axis of rotation is oriented perpendicular to the pivot axis of the pivoting device and in particular cuts the receptacle. When the rotation axis intersects the receptacle and the fibrous material web roll contained therein, the user can rotate the device particularly smoothly about the axis of rotation. Preferably, the rotating device comprises a Drehboizen, a corresponding with the pivot bolt sleeve-shaped bolt receptacle in which the pivot pin is inserted, and a fixing bolt for fixing a rotational position, which extends at least partially through the bolt receptacle and / or has a thread. Such a device is particularly advantageous because it is easy and inexpensive to implement and allows a safe rotational positioning of the device with respect to the support structure. The fixing bolt may act positively and or positively, in particular, a positive connection, for example, compared to a quick-release connection has the advantage that simple and inexpensive, a particularly secure connection is realized.

Preferably, the support structure comprises a mounting plate for fixing the support structure to a plane, for example a table, a wall or on the floor.

Further preferred embodiments of the invention can be taken from the subclaims.

FIGS. 1 to 6 show the device according to the invention for the manual production of a packaging material 3 in the form of a packaging material dispenser 10.

The packaging material dispenser 10 comprises as main components a receptacle 20 and an axial support attached thereto, which provides the roller 1 with a stop in the output axial direction A and which is realized as an output funnel 30. In addition to the illustrated conical output funnel 30 as axial support for providing an axial stop in the discharge direction for the roll 1, other tapered wall shapes are conceivable, for example, not rotationally symmetrical but only mirror-symmetrical, such as a slate cone.

The output hopper 30 has an inner wall portion _31> the tapers of the socket 20 in the direction of Ausgabeöffhung frustoconical. The opening angle of the inner wall portion 31 is about 90 °. The wall thickness of the discharge hopper 30 and its Befestigugnskragens 32 and 33 is substantially constant.

The packaging material is initially in the form of a paper web roll 1, which is unwound starting from its inner side 2 in the axial direction, so that a spiral Ve ackungsmaterialrohr 3 results. The roller 1 rests with its outer side 5 against the complementary to the roller 1 shaped inner circumference 25 of the receptacle 20, so that the receptacle 20 the roller 1 non-positively and positively engages around. A developed portion 3 of the packaging material extends outside of the packaging material dispenser 10, beyond the discharge opening of the discharge hopper 30.

The receptacle 20 is formed by a half-shell. At the front end of the half-shell, the receptacle 20 has a plurality of bolts 24 which engage in a slot 34 of the mounting collar 22, with which the discharge hopper 30 engages over the front end of the receptacle 20, and so realize a plug and bayonet connection, with the output funnel 30 is held at any orientation on the receptacle 20 and can not fall down.

At the rear end of the receptacle 20 extends an end stop 55, starting from the receptacle 20 radially inwardly. When the paper web roll 1 slips rearwardly in the axial direction A, it abuts against the end stop 55 and thereby does not fall out of the receptacle 20.

The paper web roll 1 can be inserted by the user in the radial direction R or obliquely from behind into the receptacle 20. The loading opening extends between the discharge hopper 30 and the end stop 55. On the outside of the receptacle 20, opposite the loading opening or the roller 1, the packaging material dispenser 10 has a pivoting device 60.

The pivoting device 60 comprises a receiving-side flange 61 and a mounting flange 62 and a pivot pin 63 which extends through flange 61 and 62 and defines a pivot axis S. The pivot axis S is perpendicular to the axial direction A and is usually located between the winding axis W of the paper web roll 1 and a component to which the flange 62 is attached.

The support structure-side flange 61 has a plurality of openings 65, all of which are located on a circle of constant radius around the receptacle of the pivot pin 63. Usually, the number of openings 65 is at least 3 and odd. An opening 65 is disposed (not visible) in the radial direction R below the pivot pin 63 to allow horizontal orientation of the packaging material dispenser 10.

To secure a pivotal position of the packaging material dispenser 10, a locking pin 64 is inserted through the flange 62 and a non-visible opening of the receiving-side flange 61.

Figure 2 shows a horizontally oriented packaging material dispenser 10 without an inserted paper web roll from the side.

The dispensing hopper 30 has a conically tapered inner wall portion (not visible in Figure 2), a front mounting collar 32, a rear mounting collar 33 and in between each rounded transitions. At the front mounting collar 32 is secured with two screws 42 a cutting edge with a mounting ring 40 having a plurality of teeth 41. With the teeth 41 unrolled packaging material (not shown) from the paper web roll (not shown) are separated.

The rear mounting collar 33 has snap and bayonet connection slots 34 in which corresponding bolts 24 of the receptacle 20 engage.

The receptacle 20 is also shell-shaped in FIG. 2 and its axis of rotation coincides with the winding axis W of the paper web roll (not shown).

In the front region, the receptacle 20 has a holding portion 22, which extends over more than half of the cylinder circumference of the receptacle 20. In the rear part, the receptacle 20 has a support portion 21 which engages less than half of the cylinder circumference of the cup-shaped receptacle 20. Between the support portion 21 and the holding portion 22 there is a continuous transition 23. The user can easily populate the packaging material dispenser 10 with a roller 1 by gripping the inside of the roller 1 with both hands and then inserting it into the ram opening of the receptacle 20 , The support portion 21 provides when loading the receptacle 20 only then resistance when the roller 1 is fully inserted. Once the roller comes in contact with the continuous transition 23, the elasticity of the receptacle 20 can be used so that the holding portion 22 of the receptacle 20 easily bent and the paper web roll can be easily inserted. When the paper web roll is inserted, and the holding portion 22 of the receptacle 20 on the outer periphery 5 of the roller 1 at (see: Figure 1), to prevent the roller 1 in the radial direction from the receptacle 20 slip or roll. The circumferential ends of the holding portion 22 and the support portion 21 are diametrically opposite each other.

FIG. 3 shows a horizontally oriented packaging material dispenser 10 with an inserted paper web roll 1 from above.

The paper web roll 1 is in Figure 3 with its outer periphery 5 on slightly larger inner circumference 25 of the receptacle 20 at. The inside of the paper web roll 1, which is formed by the innermost windings, is indicated by the dotted lines. By the pulling the inner end of the paper web roll 1, packaging material 3 is provided which emerges spirally from the discharge opening 11.

Bottom 4 and end 6 of the Papierbalrnrolle 1 extend in Figure 4 each in a plane. In particular, the end face 6 may (not shown) bear against an inner wall portion of the discharge hopper 30 and thereby be deformed to the discharge opening 11 out. The end face 6 is then shaped corresponding to the shape of the inner wall portion, which occurs both when pulling the packaging material 3 by pulling the adjacent to the innermost winding of the windings and when the dispenser 10 is arranged with the discharge opening 11 obliquely or vertically downwards ,

The length LI of the roller 1 in the axial direction A is here about 3 cm smaller than the length L2 of the insertion opening of the receptacle 20 between the end stop 55 and the rear mounting collar 33rd

FIG. 4 shows a packaging material dispenser 10 which is equipped with a paper web roll 1 and has an end stop in the form of a substantially fully circular plate 50.

The packaging material dispenser 10 can be equipped essentially only in the radial direction R. The opening for loading the packaging material dispenser 10 has the length L2 in the axial direction A. The roller 1 has the length LI in the axial direction A. The longitudinal dimension L2 of the loading opening is only slightly larger than the longitudinal dimension LI of the roll 1, so that a user can take the paper web roll 1 on the underside 4 and the front side and insert it into the receptacle 20, which in particular by a convex gripping recess 51 in the plate 50 is facilitated. Because the longitudinal dimension L2 is at most about 10% greater than the longitudinal dimension LI of the roll 1, a paper web roll 1, which threatens to tip out of the packaging material dispenser 10 laterally, would encounter a resistance in the form of the rear mounting collar 33 of the discharge hopper 30, so that Falling out of the paper web roll 1 is prevented from the packaging material dispenser 10.

Unlike the packaging material dispensers shown in FIG. 1 and FIG. 2, the dispensing opening shown in FIG. 4 is nevertheless oriented obliquely upwards and the flange 62 of the swiveling device 60 is oriented horizontally. Depending on what the flange 62 to he can take a defined by the fixing pin 64 and an opening 65 pivoting position.

The paper web roll 1 is partially held by the plate 50 in position. The plate 50 is substantially fully circular and therefore supports almost the entire underside 4 of the roller 1, which prevents the inner coils of the roller 1 from slipping out of the packaging material dispenser 10 due to gravity.

The plate 50 has a plurality of openings 53, which are square-shaped and arranged in a grid shape, so that the plate 50 is latticed.

The packaging material dispenser 10a is mounted to the mounting flange of a pivoting device 60 on the leg 70 of a table. The dispensing opening of the packaging material dispenser is oriented substantially vertically upwards. The plate 50 of the packaging material dispenser 10a prevents the paper web roll 1 down from the dispenser 10a falls or involuntarily unrolled down.

The dispensing opening of the packaging material dispenser 10 a is dimensioned sufficiently large so that the user 90 can grip with multiple fingers 92 and can unwind the packaging material 3 from the roll 1.

FIG. 7 shows different possibilities as to how different packaging material dispensers 10 can be mounted on a table leg 70, a table top 71 or a carrier 72. The packaging material dispenser 10a is mounted on the table leg 70 substantially as shown in FIG.

The packaging material dispenser 10b is fastened with a swiveling device 60 and a rotating device 74 on the stand 72b, which is cylindrical sleeve-shaped here and thus simultaneously forms part of the rotary device 74. With the fixing plate 77, the packaging material dispenser 10b is fixed on the table top 71. The packaging material dispenser 10b is oriented with its discharge opening obliquely left below in the direction of the table top 71.

The packaging material dispenser 10c is connected to the stand 72c via the cantilever arm 73, which is rectangular. At each end of the cantilever arm 73, the latter each has a turning device 74. A turning device 74 is located close to the stand 72c and the second immediately below the pivoting device 60 of the packaging material dispenser 10c, so that the axis of rotation D of the second rotating device 74, the receptacle 20 of the packaging material dispenser 10c and a paper web roll 1 located therein intersects. The packaging material dispenser 10d is located on a stand 72d with a mounting plate 77 which is fixed directly to the floor and otherwise resembles the stand of the packaging material 10b.

The stand 72e of the packaging material dispenser 10e has five rolling wheels 78. At least one of the wheels 78 can be locked, preferably 2, so that the stand 72e of the packaging material dispenser 10e is prevented from involuntarily rolling away. The features disclosed in the foregoing description, the figures and the claims may be of importance both individually and in any combination for the realization of the invention in the various embodiments.
